What is Custom Concrete? Where is Shotcrete Used?
Custom concrete is the name given to concretes manufactured to satisfy customer expectations that differ from the properties of normal concrete based on the area of application. In our series on custom concrete, the definition and importance of certain types of custom concrete as well as the materials, the blend ratios, their characteristics and areas […]
Pouring Concrete: Key Considerations for Pouring Concrete in Hot Weather
When pouring concrete, the ambient temperature is critical. If the measures that should be taken when pouring concrete in hot weather are not implemented, concrete strength will be negatively affected. Concrete hardens as a result of a chemical reaction, and the speed of this reaction increases as the temperature increases. At high temperatures, rapid hydration results […]
What is Fly Ash? What is the Use of Fly Ash in Cement?
Fine-grained mineral additives are mixed together with the basic materials used in concrete production (cement, aggregate and water) and included in the concrete mixture. The proportion in which they are used is usually 10%-50% of the amount of cement contained in the concrete mixture. Fine-grained mineral additives affect many properties of fresh and hardened concrete, […]
What is Concrete Road?
Concrete road is a superstructure paving type which is made with concrete building material, and which conveys the axle loads to the base. Concrete roads enable different designs for different load traffic. They provide a flexible design. We can summarize the advantages of concrete road as follows: Çimsa Concrete Road Pilot Project In this section, […]
Compressive Strength of Concrete: What Is Blast Furnace Slag?
Granulated blast furnace slag is a mineral additive which in fact is an industrial waste, produced during the production of pig iron in iron and steel factories. Since they have a siliceous and aluminous amorphous structure, blast furnace slags show pozzolanic properties when they are ground to a very fine grained state. When the hydration […]
What are the Hydration Stages? How is Durable Concrete Created Based on the Stages of Hydration?
Hydration is a series of irreversible chemical reactions between cement and water. During hydration, cement-water paste sets and hardens. Hydration begins as soon as cement comes into contact with water. The cement particles slowly, partially dissolve, and the various dissolved components start to react at various rates. During the reactions, heat is generated, and new […]
What is Clinker? The Relationship Between Clinker Phases and Grinding Parameters
Clinker is the primary material of cement, and it is called as semi-finished product. Clinker is a granulated material made of raw meal powder obtained by grinding limestone and clay together by sintering the raw meal in a rotary furnace at 1400°C-1500°C degrees. Produced clinker’s mineralogical structure effects clinker’s grinding energy. And it determines the […]
Prefabricated Manufacturing: How to Apply Steam Curing in Prefabricated Structural Component Manufacturing?
Strength gaining rate increases when concrete curing temperature is kept at elevated levels. Steam curing is applied on concrete components in order to have high early strength. Atmospheric steam curing is applied in 4 intervals on prefabricated concrete construction components in order to obtain higher strengths in the first days and acceptable strengths at later […]
Pouring Concrete in Cold Weather: Key Considerations
Pouring concrete in cold weather may cause problems with concrete strength and durability. In this article, we will discuss with you what kind of precautions can be taken when pouring concrete in cold weather, and all of the factors that must be taken into consideration. Six Precautions to Take Prior to Pouring Concrete in Cold […]
What is hydration? How Does Cement Hydration Take Place?
A few hours after the concrete components are mixed, concrete components form a solid structure that loses its plastic properties. The reason for this is the chemical reaction between cement and water known as hydration. The cement paste which was initially soft plastic, becomes less plastic as time progresses and solidifies and hardens. The chemical […]
